WATER Application filed July 17,

This invention relates to new and im proved constructions of hot water bottles made of rubber. The object of the invention is to improve upon the construction and design at the neck of the bottle so as to make it stronger and better able to resist the heat and pressure to which the bag is SHb]6Ctd in service.

One of the chief causes of failure of hot water bottles is the insecure fastening about the plug at the mouth of the bottle. These plugs, which contain the socket or seat for the hot water bottle stopper, are molded as separate pieces and. cemented orvulcanized in the neck of the bottle. With no further means for holding the plug in position, the bottle will tend to open around the edge of the plug. Earlier forms of hot water bottles have employed circumferential binding wires about the bottle neck, but this construction is unsightly and expensive. By the construction shown in this application, the weaknesses of the bottle at this point have been overcome without the objectionable wire and there is no liability of separation of the wall of the bottle from the plug.

This object is obtained by providing interlocking or mating formations between the wall of the bottle and the plug.

In the drawings is shown the preferred form of the invention, it being understood that changes and modifications may be made therein without departure from the principles or mode of operation of the device.

Figure 1 is a side view of a water bottle constructed in accordance with the present invention and showing one embodiment thereof:

Figure 2 is an enlarged section through the mouth of the bottle; and

Figure 3 is a section on the 1ine3-3 of Figure 2.

The bottle comprises the usual body portion 1 and restricted neck 2 which terminates in the funnel 3. The plug 4 of the bottle is formed in any suitable shape, the usual construction being in the form of an oval. This plug is made of a. hard rubber or mixture of rubber and suitable filling material. It has embedded within it the screwthreaded socket 5 for receiving the stopper 6. This plug is usually molded as a separate piece from the balance of the bag and then vulcanized or cemented in the neck of the bag.

In order to insure that the plug will be securely seated and held within the bag, the plug and wall of the bag are formed with a mating interlocking groove and rib which, when the bag is completed, form an effective barrier or interlock between the plug and the neck of the bag. As shown herein, -the plug is formed with a series of circumferential grooves 10 and the neck of the bottle with correspondingly shaped ribs 11 which seat within the grooves. As shown there are three of these grooves and ribs, the center being somewhat deeper than the outer ones, but the arrangement, location and number of grooves and ribs may be varied. It is also possible to form ribs upon the plug and grooves in the wall of the neck, but the construction shown is preferred.

It'will be seen that a very effective and simple interlock between the plug and the neck of the bottle has been provided which will obviate the difficulties heretofore encountered and make a water-tight bag which Will resist pressures and temperatures and securely seal the contents of the bag, reventing failures about the neck or lug of the bottle and preventing the )lug rom being withdrawn or loosened. T is has been accomplished without the provision of the unsightly and expensive wiring heretofore used, and eliminates this objectionable feature of other water bottle constructions.

What is claimed is:

1. A hot Water bottle comprising a body and a neck portion, a rubber plug within the neck portion and having a threaded socket member embedded therein, and mating grooves and ribs between the plug and the neck of the bottle.

2. A hot water bottle comprising a body and a neck portion, a plug of rubber ad hesively secured within the neck portion said plug having a threaded socket therein, and mating interlocking formations between the neckportion of the bottle and the plug.

3. A hot water bottle comprising a body and a neck port-ion, a rigid, rubber plug within the neck portion, the plug being provided with circumferential grooves about its periphery and ribs formed integrally with the neck portion and seated within the grooves, the plug being permanently secured within theneck of the bottle by adhesion and the edge about the plug sealed by said grooves and ribs, said plug having a stopper receiving socket member embedded therein.

4-. A hot Water bottle comprising a body and a neck portion, a rigid, rubber plug 5 Within the neck portion, the plug being provided with a circumferential groove about its periphery and a rib formed integrally with the neck portion and seated within the groove, the plug being permanently secured within the neck of the bottle by adhesion 10 and the edge about the plug sealed by said groove and rib, said lug having a threaded socket member e'mbe ded therein.
